Notes On The Non Linear Operator Equation I AXAX n  *

Ibn Al-Haitham Journal for Pure and Applied Sciences, 2016
  Necessary and sufficient conditions for the operator equation I AXAX n  * , to have a real positive definite solution X are given. Based on these conditions, some properties of the operator A as well as relation between the solutions X ...

Matrix Sylvester equations in the theory of orthogonal polynomials on the unit circle [PDF]

, 2010
In this paperwe characterize sequences of orthogonal polynomials on the unit circle whose Carathéodory function satisfies a Riccati differential equation with polynomial coefficients, in terms of matrix Sylvester differential equations.

Positive solutions for a nonlinear parameter-depending algebraic system [PDF]

, 2015
Through variational methods, the existence of positive solutions for a nonlinear parameter-depending algebraic system is investigated. The main tools used are some very recent critical points theorems on finite dimensional Banach spaces and a new ...

The geometry of convex cones associated with the Lyapunov inequality and the common Lyapunov function problem [PDF]

, 2005
In this paper, the structure of several convex cones that arise in the study of Lyapunov functions is investigated. In particular, the cones associated with quadratic Lyapunov functions for both linear and non-linear systems are considered, as well as ...
